Chasing Linux mount point indirection

It can be a challenge to track down what mount point on a Fedora/RHEL Linux box belongs to which physical disk partition when there are several layers of indirection including Logical Volume manager, Encrypted Disks and UUIDs. Fortunately, the computer does it for us most of the time. But when I, as a human being, […]

Why Linux?

I’ve acquired a used desktop computer with 6GB RAM, and I’ve been trying to figure out whether to put Linux or Windows 7 on it in the long term. I’d like it to be useful to the whole family. Windows 7 is great for playing DVDs, Youtube movies, doing Netflix streaming, games, printing to our […]

Linux tty auditing

Since RHEL 5.4, and in recent Fedora releases, it’s possible to audit what users type at their tty (command prompt), thanks to the work of Steve Grubb, a RedHat employee. Edit /etc/pam.d/system-auth and append the following, but not both: session required pam\_tty\ disable=\* enable=root session required pam\_tty\ enable=\* Wait for users to log in and […]

Gnome 3: Not quite ready for prime time

Just over a week ago, I installed Fedora 15. After using Gnome 3 for two days, I decided that I’m better off using Gnome 2, KDE or XFCE. With Gnome 3, I like the ability to type the name of the application I want to run instead of hunting for it in a menu. This […]

Fedora 14, SSH ports and SELinux

SELinux in Fedora 14 is configured to constrain the ports on which SSH can listen (see the bug report). The solution: setsebool -P sshd_forward_ports 1 This allows SSH to listen on ports besides 22, and to forward ports. Reading the bug report is interesting. In my opinion, OpenSSH has an outstanding security track record, and […]

Miscellaneous Linux tips and tricks

Gnome Key Bindings and IntelliJ IDEA IntelliJ IDEA key bindings conflict with Gnome’s window manager. In IDEA, I can type CTRL-B to jump to a symbol definition. Normally, I’d type CTRL-ALT-LEFTARROW to navigate back to where I had come from. Gnome’s MetaCity intercepts that key mapping before IDEA sees it, and tries to move my […]

f-spot and sqlite

I recently tried using Linux [f-spot](, with the intent to make it easier to browse, manipulate, manage and publish my photos. I wanted f-spot to manage my photo screen saver as well. f-spot seems to be good at importing photos, but getting photos removed is a bit more difficult. I organize my photos by date […]

Using rsync with SELinux

Last week, I needed to move /home from one Fedora computer to another, and I used rsync over ssh move the data. On the new system, I noticed that procmail didn’t seem to be working, and neither did Dovecot. Nor could apache serve up my files. This had all been working on my previous Fedora […]

Fedora 11 and Virtualization (KVM)

I’ve recently upgraded another computer from Fedora 9 to Fedora 11, and I’ve decided to try the built-in [KVM]( (i.e. Applications -> System Tools -> [Virtual Machine Manager]( I wanted a virtual machine that had bridged mode networking, but it wasn’t available by default. To get it as an option, I disabled SELinux (not sure […]

My impressions of Fedora 11

Here’s my take on installing Fedora 11, which was released June 9, 2009. I chose not to do an upgrade as I often do. Instead, I did backup, followed by a fresh install, preserving my /home partition, but wiping out the other partitions. Then I used [`meld`]( to restore my configuration files in /etc — […]
